* Rename F_{None,Text,Append} to OF_{None,Text,Append}. NFCFangrui Song2019-08-051-1/+1
| | | | | | F_{None,Text,Append} are kept for compatibility since r334221. llvm-svn: 367800
* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-192-8/+6
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* Pass a reference to a module to the bitcode writer.Rafael Espindola2018-02-141-1/+1
| | | | | | | This simplifies most callers as they are already using references or std::unique_ptr. llvm-svn: 325155
* [Support] Rename tool_output_file to ToolOutputFile, NFCReid Kleckner2017-09-231-2/+2
| | | | | | | This class isn't similar to anything from the STL, so it shouldn't use the STL naming conventions. llvm-svn: 314050
* Bitcode: Add a string table to the bitcode format.Peter Collingbourne2017-04-171-3/+6
| | | | | | | | | | | | | | | | | | | | | | | Add a top-level STRTAB block containing a string table blob, and start storing strings for module codes FUNCTION, GLOBALVAR, ALIAS, IFUNC and COMDAT in the string table. This change allows us to share names between globals and comdats as well as between modules, and improves the efficiency of loading bitcode files by no longer using a bit encoding for symbol names. Once we start writing the irsymtab to the bitcode file we will also be able to share strings between it and the module. On my machine, link time for Chromium for Linux with ThinLTO decreases by about 7% for no-op incremental builds or about 1% for full builds. Total bitcode file size decreases by about 3%.

* Add llvm-modextract tool.Peter Collingbourne2016-11-293-0/+104
This program is for testing features that rely on multi-module bitcode files. It takes a multi-module bitcode file, extracts one of the modules and writes it to the output file. Differential Revision: https://reviews.llvm.org/D26778 llvm-svn: 288201
